Hot Deformation and Processing Window Optimization of a 70MnSiCrMo Carbide-Free Bainitic Steel

The hot deformation behavior of a high carbon carbide-free bainitic steel was studied through isothermal compression tests that were performed on a Gleeble-1500D thermal mechanical simulator at temperatures of 1223-1423 K and strain rates of 0.01-5 s-1. The flow behavior, constitutive equations, dynamic recrystallization (DRX) characteristics, and processing map were respectively analyzed in de...

Some Applications of Neural Networks for Condition Monitoring in Industrial Systems for Hot Dip Zinc Galvanizing

The paper describes the abilities of some particular neural network structures (NNS) to provide condition monitoring in a real industrial system, designated for hot dip zinc galvanizing. Condition assessment of a molten zinc bath furnace, and more specifically analysis and prediction of the technical condition in galvanizing kettle walls are also developed in this paper.

REACTION KINETICS OF THE FORMATION OF INTERMETALLIC Fe – Zn DURING HOT - DIP GALVANIZING OF STEEL

P. Pokorny, J. Kolisko, L. Balik – Czech Technical University – Klokner Institute, Prague, Czech Republic P. Novak – Institute of Chemical Technology, Prague, Czech Republic This review article mainly describes the composition of intermetallic Fe Zn, i.e. zeta (ζ), delta (δ1k + δ1p), gamma1 (Γ1) and gamma (Γ) on galvanized steel during low temperature galvanization (t ~ 450 °C). It gives detail...

Treatment of spent pickling baths coming from hot dip galvanizing by means of an electrochemical membrane reactor

The performance of a one (OCR) and a two-compartment electrochemical reactor in the presence of a cation-exchange membrane (CEM) for the zinc recovery present in the spent pickling baths is analyzed in this paper under galvanostatic control. These solutions, which mainly contain ZnCl2 and FeCl2 in aqueous HCl media, come from the hot dip galvanizing industry. The effect of the applied current, ...
